BURNER.

To all whom it may concern:

Be it known that I, EDWIN DE Lon, a citizen of the United States,residing at Bartlesville, in the Cherokee Nation, Oklahoma, haveinvented certain new and useful Improvements in Burners; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in vapor andgaseous fuel burners and it has particular reference to a burner for usein furnaces and comprising generally a supply pipe formed with aaporizing coil and provided with burners proper below said coil.

The invention has for its object to provide a burner of novelconstruction in which the flame shall be always uniform and in which theliability of the burner becoming clogged is reduced to a minimum.

The invention aims as a further object to provide a novel construction,combination and arrangement of parts, the details of which will appearin the course of the following description, in which reference is had tothe accompanying drawings, formin a part of this specification, likecharacters of refer ence designating similar parts, throughout theseveral views, wherein:

Figure 1 is a sectional view through a furnace illustrating the mannerof use of a burner constructed in accordance with the present invention.Fig. 2 is a topfjplan view of the fuel supply pipe showing the relativearrangement of the coil and the burner. Fig. 3 is an elevation of theburner showing in detail, the curved formation of the flame o ening.Fig. 4 is a section on the line 4-41 of Fig. 3.

In the accompanying drawings, the nu- Ineral 10 designates a steamboiler furnace rovided with a steam dome 1.1. Within the furnace is apipe 12 having its body portion formed with a vaporizing coil 13, andrearwardly of said coil being bent recurvately as at 14. The portion 14lies beneath and in parallelism to the body of the pipe 12 and hasconnection by means of a T oint 15 with a cross ipe 16. The latter, atits ends, carries elfiow joints 17 which are in turn coupled with pipes18 and the latter carry the burn ers 19, disposed on each side of thecoil 13.

The pipe 12, at its outer end has connection Specification of LettersPatent.

with a jet 20 and the latter is likewise in communication with a pipe21, leading from the dome 11, the pipe 21 being provided with acontrolling valve 22 in order that the supply of steam which is used toinduce the feed of oil and combustion may be regulated as desired.

The j et 20 likewise has connection with an oil supply pipe 23 leadingfrom a tank or reservoir 24. The burners 19, at each side of the coil13, are counterparts in construction. Each of said burners is in theform of a metallic cap having a cylindrical body 25 and an upper closureplate 26 which is preferably integral. At points diametrically oppositeof the body 25 curved slits 27 are cut thereinto. These slits extendupwardly in diverging relation to one another so that the flames divergefrom each side of the burners, the said slits terminating at oppositepoints of the junction of the plate 26 with the body 25.

The provision of the slits 27 in the relation stated assures of the twoflames from each burner being uniform and constant at all times. Theseslits are not liable to become clogged or choked and the flames havemaximum heat and effect upon the coil 13 with a minimum consumption offuel. In order that best results can be obtained from the flames, theslits extend upwardly from a roximately centrally of the height of tiebdurner and converge outwardly to the upper edge of the burner.

The invention is simple in its structural details, inexpensive tomanufacture and practical and efficient in use.

From the foregoing description it will be seen that simple and efficientmeans are provided for accomplishing the objects of the shown anddescribed are well adapted to serve the functions set forth, it isobvious that various minor changes may be made in the proportions, shapeand arrangement of the several parts, without departing from the spiritand scope of the invention as defined in the appended claims.

\Vhat is claimed is:

1. A heating gas burner consisting of a hollow cylindrical cap havingone end closed, said cap being provided with egress slits extendingdiametrically opposite points of the extreme upper edge of the side wallof the cap, convergingly in the direction of the open end of the cap.
